I had Gregg's come and do a furnace check up through Groupon. Both guys were very friendly and professional. They were sure to help me understand what they were doing and why (which is important as a first time homeowner!). They noticed that the furnace hadn't been inspected since installation and let me know who to contact to arrange the inspection. They also made sure I knew what the potential issues were to bring up with the inspector. All this was enough, but they also checked my garage furnace to ensure it was running well too! I will definitely use Gregg's from here on out!
